Problems solved by technology
When the steel coil is used in the workshop, a crane is needed. When the existing crane spreader is hoisting the steel coil, the steel coil needs to be manually installed on the spreader, and the installed steel coil is difficult to rotate, and the steel coil cannot be carried out. Rewinding operation, so a self-rotating steel coil spreader is required

Description
technical field [0001] The invention relates to the field of crane spreaders, in particular to a self-rotating steel coil spreader of an unmanned automatic crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and transports heavy objects horizontally within a certain range. The crane mainly includes a lifting mechanism, an operating mechanism, a luffing mechanism, a slewing mechanism, and a metal structure. The hoisting mechanism is the basic working mechanism of the crane, mostly composed of a suspension system and a winch, and also lifts heavy objects through a hydraulic system. The operating mechanism is used to move heavy objects vertically and horizontally or adjust the working position of the crane, and is generally composed of a motor, a reducer, a brake and wheels. The luffing mechanism is only equipped on the jib type crane. When the jib is raised, the range decreases, and when it is lowered, the range increas...
